help with ISC Kea dhcp and iPXE

[fdge]

Here is part of the config that is working in my test setup

Code:

"client-classes":
    [
      {
        "name": "XClient_iPXE",
        "test": "substring(option[77].hex,0,4) == 'iPXE'",
        "boot-file-name": "http://<ServerIP>:<ServerPort>/<path>/<PHPfile>"
      },
      {
        "name": "UEFI-32-1",
        "test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00006'",
        "boot-file-name": "ipxe/i386/ipxe.efi"
      },
      {
        "name": "UEFI-32-2",
        "test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00002'",
        "boot-file-name": "ipxe/i386/ipxe.efi"
      },
      {
        "name": "UEFI-64-1",
        "test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00007'",
        "boot-file-name": "ipxe/x86_64/ipxe.efi"
      },
      {
        "name": "UEFI-64-2",
        "test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00008'",
        "boot-file-name": "ipxe/x86_64/ipxe.efi"
      },
      {
        "name": "UEFI-64-3",
        "test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00009'",
        "boot-file-name": "ipxe/x86_64/ipxe.efi"
      },
      {
        "name": "Legacy",
        "test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00000'",
        "boot-file-name": "ipxe/undionly.kpxe"
      }
    ]

and to allow BIOS PXE I needed to use the patch from
https://www.mail-archive.com/ipxe-devel@...05268.html

Code:
